AEG M4 Magazine Lip Feed Replacement

A replacement magazine lip/feed piece designed for DMAG AEG airsoft M4-style magazines.
This model was recreated as close as possible to the original part and tested on my own replica for proper fitment and feeding performance.

Features

• Replicated almost 1:1 from the original part
• Snug and secure fitment
• Tested in magazine and rifle for reliable BB feeding
• Simple replacement part for worn or cracked magazine lips

Compatibility

Confirmed fitment with:

> Battle Axe & EC-style DMAG M4 AEG magazines

May also fit other generic DMAG AEG polymer magazines using similar lip feeder style or even some high-cap magazines using the same design

Because manufacturers often use slightly different tolerances, fitment with other brands may vary!

Creator Note

The part tight fitted & tested for feeding performance, and it performed reliably during use. Depending on your printer tolerances, minor sanding or cleanup may improve fitment.

I personally used horizontal orientation which worked well for me, but feel free to experiment with different rotations and support setups for the best results on your printer.

Also, this is my first ever 3D model created basically from scratch, so feedback is very welcome.
If anyone has recommendations for optimization, durability improvements, tolerance adjustments, or general modelling tips, feel free to share them as I’d genuinely appreciate the input.

Hopefully someone else finds this as useful as I did :)
